People who live in __________ are the most likely to be exposed to nitrate and phosphate pollution in surface and ground water.
A)
fishing villages
B)
rural farming areas
C)
mountainous areas with reduced oxygen levels
D)
urban industrial areas
Answer:
B) rural farming areas
Explanation:
Phosphate and Nitrate are two common pollutants that affect surface and ground water. They result mostly from the fertilizer used in farming operations. This is because fertilizer contains these nutrients to improve the fertility of the soil in which the crops are planted, however, they manage to get eroded into water bodies when it rains.
Due to that fact that most farming occurs in RURAL AREAS, people that live in rural farming areas are most likely to be affected by the effects of nitrate and phosphate pollution in their water bodies (surface and ground).

Scientists determine evolutionary relationships between animal phyla using evidence from the a. fossil record. c. animal size. b. number of offspring. d. animal behavior.
Answer:
The correct answer is - a. fossil record.
Explanation:
Fossil records are the records or list of fossils that are analyzed and placed in order taxonomically. Fossils are very helpful in establishing the evolutionary relationship of the animal phyla by various ays such as the age of a fossil by dating, DNA, or genetic material helps them to determine the evolutionary relationships of various species or organisms. It helps in representing the changes that took place in organisms over the period of time.
Thus, the correct answer is - a. fossil record.

Microvilli are found on cells of the inner surface of the small intestine, where they Microvilli are found on cells of the inner surface of the small intestine, where they increase the absorption of nutrients from digested food. protect the intestinal lining from irritants or toxins in the food. push food along the digestive tract. slow the movement of food through the digestive tract. sense the presence of food in the digestive tract.
Answer:
increase the absorption of nutrients from digested food.
Explanation:
MICROVILLI are structures found on the surface of body organs such as small intestine. They help the small intestine mainly to perform its absorptive function. In other words, microvilli increase the absorption of nutrients from digested food.
Microvilli aid in this absorptive function by increasing the surface area of the small intestine and hence, allow more nutrients to be absorbed from digested food.
Select all the advantages of a multienzyme complex over a metabolic pathway
A. There is less room for substrates to diffuse away
B. Each enzyme can be activated or inhibited individually
C. The product of one enzyme will serve as the reactant for the next
D. The complex can be regulated as a group
Answer:
Option A, B, C
Explanation:
The major advantages of multienzyme complex over a metabolic pathway is that it do not require individual pathway for each enzyme activation or inhibition. Instead it responds efficiently to the equilibrium changes of substrate supply and demand as compared to that of enzymes.
It tightly regulates the processes and is also faster than that of the metabolic pathway.
Hence, option A, B and C are correct
The cell membrane contains channels and pumps that help move materials from one side to the other. What are these channels and pumps made of?
Group of answer choices
carbohydrates
proteins
lipids
nucleic acid
Answer:
The correct answer is ''proteins.''
Explanation:
Transport phenomena are essential in living beings, either to carry a hydrophobic molecule through an aqueous medium (transport of oxygen or lipids through the blood) or to transport polar molecules through hydrophobic barriers (transport through the cell membrane). Biological transporters are always proteins. Proteins are capable of carrying out specific functions such as the selective transport of molecules, or certain enzymatic reactions, among others. Membrane proteins can be peripheral or partially or totally integrated into the membrane, being, generally, globular or fibrous. Its activity is essential for the maintenance of transmembrane gradients. Thanks to membrane proteins, the exchange of molecules such as nutrients or waste products takes place, as well as the reception of external signals. Among its functions are channel-forming: Integral proteins arranged in the membrane in such a way that they give rise to the formation of a pore or channel, usually hydrophilic. These pores or channels allow the entry and exit of certain substances from the cell.

Where do the thickest deposits of terrigenous sediment typically form?
A. deep-ocean trenches, such as the Mariana Trench
B. mid-ocean ridges
C. abyssal plains
D. continental margins near the mouths of rivers
Answer: D. continental margins near the mouths of rivers
Explanation:
Terrigenous sediments are those that are formed via processes on land as opposed to in water. They result mostly from the erosion of rocks and yet make up 20% of all ocean sediments.
Continental margins near the mouths of rivers contain the thickest deposits of this sediments as they are closest to land which is the source. It is made more convenient by the presence of rivers bringing the sediments to them when the rocks are eroded.

You have a large bottle of 2% saline solution in the lab (2% NaCl, which is sodium chloride). You need 5 ml of 0.1% saline for an experiment. Do the calculation for the dilution you would need to make (i.e., calculate the volume of 2% saline and the volume of water you would need to combine).
Answer:
volume of 2% saline (V₁) = 0.25ml
volume of water = 4.75ml
Explanation:
The requirement in the question is to obtain 0.1% of NaCl from 2% NaCl, and the process is dilution. The general dilution equation is guven by:
C₁V₁ = C₂V₂
where:
C₁ = initial concentration = 2%
V₁ = initial volume = ?
C₂ = final concentration = 0.1%
V₂ = final volume = 5ml
C₁V₁ = C₂V₂
calculating for V₁
∴ V₁ = (C₂V₂) ÷ C₁
= (0.1% × 5) ÷ 2%
V₁ = 0.25ml
Now, let us calculate the volume of water needed:
V₁ + Volume of water = V₂ (volume of 0.1% NaCl)
0.25 + volume of water = 5
volume of water = 5 - 0.25
volume of water = 4.75ml

20. Which statement correctly categorizes hog operations?
O A. Feeder operations raise hogs throughout their lifetime, farrow-to-finish operations raise young hogs, and finisher operations raise older hogs
O B. Feeder operations raise hogs throughout their lifetime, finisher operations raise young hogs, and farrow-to-finish operations raise older hogs
O C. Finisher operations raise hogs throughout their lifetime, feeder operations raise young hogs, and farrow-to-finish operations raise older hogs.
O D. Farrow-to-finish operations raise hogs throughout their lifetime, feeder operations raise young hogs, and finisher operations raise older hogs
Answer:
D. Farrow-to-finish operations raise hogs throughout their lifetime, feeder operations raise young hogs, and finisher operations raise older hogs
Explanation:
Hog farms operate in three different categories:
Farrow-to-finish: This involves breeding sows to produce offspring. The offspring's are then fed until they are have reached the size for slaughter. The entire process takes throughout the hogs lifetime.
Feeder operations: This involves breeding sows and then selling their piglets to other farmers who will then raise them for till they are matured for slaughters. This process is just to raise young hogs.
Finisher operations: This involves buying piglets from other farmers and then raising them until they are matured for slaughter. This finisher operations raise older hogs
what is the function of DNA, and why is it called the heritable material
Answer:
DNA is an information molecule.
Explanation:
WHAT IS THE FUNCTION OF DNA?
DNA stands for Deoxyribonucleic acid.
It allows the body to tell it how to make larger proteins. It contains 46 chromosomes.Chromosomes are 1 strand of DNA. (Imagine your hair. Your whole head of hair is like DNA, if you were to pull out 1 string of hair, it would be a chromosome.)WHY IS IT KNOWN AS A HERITABLE MATERIAL?
It is known as a heritable material because your parents pass their genes onto you.
(If you cut your 1 strand of hair (chromosomes) into pieces then it would be a gene.)
Part of your fathers genes and mothers genes join to make up your DNA by passing on their genes to you.

remained short for several centuries, then became much taller over the last 50 years. have consistently grown taller over the last two centuries. vary in height primarily because of the degree of various stressors on each population. vary in height because of genetic differences between groups.
Answer:
Vary in height primarily because of the degree of various stressors on each population
Explanation:
Shorter plants became taller because of the various stressors such as unavailability of sunlight. Due to unavailability of sunlight, the plants grow taller for gaining solar radiation that is required for the process of photosynthesis. So we can say that the environmental condition or stress brought changes in the plant body.
